3 ProjectWOLLONGONG CITY COUNCILG eneral CommentsThe analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house developed procedures are employed in the absence of documented standards or by client moisture determination has been performed, results are reported on a dry weight a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix sampling time information is not provided by the client, sampling dates are shown without a time component.

4 In these instances, the time component has been assumed by the laboratory for processing a result is required to meet compliance limits the associated uncertainty must be considered.
